A Study to Investigate the Efficacy, Safety, and Tolerability of AZD4144in Participants With Sepsis-associated Acute Kidney Injury.

Inclusion Criteria Age ≥ 18 to ≤ 80 years at the time of signing the informed consent. Participants who are admitted to an ICU or an equivalent critical-care unit. Diagnosis of sepsis according to criteria defined by The Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3) based on: A. Suspected or confirmed bacterial infection AND B. Acute increase of mSOFA score of 2 or more excluding renal component (change in score measured to account for participants that may meet mSOFA criteria from pre-existing organ dysfunction before the onset of infection). Haemodynamic therapy: A. 30 mL/kg or clinically appropriate volume resuscitation prior to randomisation. B. Vasopressor and/or inotrope therapy for sepsis-induced hypotension (eg, norepinephrine \[noradrenaline\], epinephrine \[adrenaline\], phenylephrine, dopamine, dobutamine) for ≥ 4 hours. Diagnosis of AKI, within 72 hours of sepsis diagnosis, with modified KDIGO Stage ≥ 1, defined as: Increase in SCr to ≥ 1.5 × baseline (outpatient \[preferred\] or admission pre-AKI reference). Timing of AKI diagnosis is defined as the time that the initial qualifying SCr was reported. AKI must persist after completion of initial volume resuscitation (30 mL/kg or as clinically indicated per investigator discretion). Outpatient pre-AKI reference eGFR ≥ 30 mL/min/1.73 m2, if available within 2 weeks to 12 months prior to admission (preferred). If not available, admission pre-AKI reference eGFR ≥ 45 mL/min/1.73…
